I completed my post-graduation in 2013 in the engineering field. Engineering is the application of science and math to solve problems. Engineers figure out how things work and find practical uses for scientific discoveries. Scientists and inventors often get the credit for innovations that advance the human condition, but it is engineers who are instrumental in making those innovations available to the world. I love pet animals such as dogs, cats, etc.

Can you answer this question?

There are two ways to convert an enum to an int in C#:

  1. Using the ToInt() method.
  2. Using the value property.

Using the ToInt() method

The ToInt() method takes an enum as its parameter and returns the corresponding integer value. The following code converts an enum to an int:

C#

enum Color { Red, Green, Blue }

int red = (int)Color.Red;

In this code, the ToInt() method is used to convert the Color.Red enum to an int. The result is the integer value 0, which is the underlying value of the Color.Red enum.

Using the value property

The value property of an enum returns the underlying integer value of the enum. The following code also converts an enum to an int:

C#

enum Color { Red, Green, Blue }

int red = Color.Red.value;

In this code, the value property of the Color.Red enum is used to get the underlying integer value, which is 0.

Which method you use to convert an enum to an int depends on your preference. The ToInt() method is more explicit, as it explicitly specifies that you are converting the enum to an int. However, the value property is more concise and easier to read.
